The van was strong, although it was built of light boards like a dove-cot.

In front there was a glass door with a little balcony used for orations, which had something of the character of the platform tempered by an air of the pulpit.

At the back there was a door with a practicable panel.

By lowering the three steps which turned on a hinge below the door, access was gained to the hut, which at night was securely fastened with bolt and lock.

Rain and snow had fallen plentifully on it; it had been painted, but of what colour it was difficult to say, change of season being to vans what changes of reign are to courtiers.
